SPARK OR CINDER ARRESTER OR COLLECTOR.

Specification of Letters Patent.

Patented Sept.. ill, tgl?.

Application filed July 22, 1916. Serial No. 110,813.

To all whom t may concern:

Be it known that we, IsAAo J. SHIFLEY and GEORGE WOLFGANG, oi Tampa, inthe county of Hillsborough and State of Florida, have invented certainnew and useful Improvements in Spark or Cinder Arresters or Collectors;and we do hereby declare the following to be a full, clear, and exactdescription thereof, su'liicient to enable others `skilled in the art towhich the invention appertains to make and use the same, reference beinghad to the accompanying drawing and to the letters of reference markedthereon.

Our invention relates to a spark or cinder collector or arrester, foruse on smoke stacks or steam engines; the objects of the invention are:

lst. To prevent fires from sparks and cinders.

2nd. rIo prevent the emission or expulsion of sparks and cinders fromsmoke stacks or steam engines.

3rd. To collect these sparks and cinders and to provide an outlet forthem and to convey them to any suitable place.

4th. Not to choke or retard the draft of the smoke stack.

We attain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a view or plan showing the device inposition or installed on the smoke stack of a locomotive engine; Fig. 2is a vertical section of the device on the smoke stack of a locomotiveengine; Fig. 3 is a view or section of the device, looking down thesmoke stack after the installation of the devices.

The device consists of a number of inclined walled annuli or disks, A,A, etc., Fig. 2, the number and size to be regulated by the size of thesmoke stack; they are connected by three or more hangers or braces.

The sides of the disks, 1-2, 3, 4, 5-6, 7, 8, and 9--10, are inclinedfrom their lower edges upwardly and outwardly, or so arranged that theupper edges protrude beyond the lower edges of the disks above and alsothat the sides point or slope toward the point l0 in Fig. 2 so that thesparks or cinders will be deflected when they strike these disks topoint 10, which is the rim or top of the device; the sparks or cindersfall from point l0 or the rim on to the base, which is concave orsloping, and roll to and are collected at the lowest point 2-2 in Fig.l. They are carried off in pipes AA in Y Fig. l, or C in Fig. 2. y Thesepipes lead to the ground or to any convenient place.

The lower disk is in the shape of a cone pointed at the bottom and issolid. All the other disks have no bottom or top but are y open for theemission of smoke and steam.

The device is larger than the smoke stack to provide for eXtra air spaceand to prevent choking and not to interfere with the draft.

The device is fastened to the smoke stack by rivets or bolts.

I-Iaving thus fully described our invention, what we claim and desire tosecure by Letters Patent of the United States, is-

In a separator of the class described, an'

inner tubular member, an outer tubular member spaced from said innermember and having a flooring attached to the outer wall of said innertubular member, and provided with an annular baiile member projecting inwardly and overhanging the upper edge of said inner member and aplurality of supplemental baffle members of successive decreasingbaii'iing area supported by said annular baille member within said innertubular member, a discharge pipe extending from said flooring for thedischarge and collection of matter.
